[PATCH] xfstests: include NIS databases

To: xfs@xxxxxxxxxxx
Subject: [PATCH] xfstests: include NIS databases
From: Alex Elder <aelder@xxxxxxx>

If NIS is active on a test target system, additional password and
group file information is available via their respective databases
in NIS.  Currently, some tests assume that /etc/passwd and /etc/group
are the only places to find this information.

This patch causes both the local database and the NIS database (if
one is likely to be present) to be consulted for needed information.
